This patch replaces the parameters provided to a service through `params` by the contract object. That way, it allows better consistency when accessing input params. For example, if you have a service without a contract, to access a parameter, you need to use `params[:my_parameter]`. But with a contract, you do this through `contract.my_parameter`. Now, with this patch, you’ll be able to access it through `params.my_parameter` or `params[:my_parameter]`. Some methods have been added to the contract object to better mimic a Hash. That way, when accessing/using `params`, you don’t have to think too much about it: - `params.my_key` is also accessible through `params[:my_key]`. - `params.my_key = value` can also be done through `params[:my_key] = value`. - `#slice` and `#merge` are available. - `#to_hash` has been implemented, so the contract object will be automatically cast as a hash by Ruby depending on the context. For example, with an AR model, you can do this: `user.update(**params)`.
